I invested $19.99 in this game today.
I've completed 6 of 90 quests in just a couple of sessions, fairly simple gameplay (as might be expected in a game aimed at 4-12 YOs), it plays much like the online games we've seen lately with sidescrolling 2D platform sections (akin to the old Mario games), and a top-down flying section on the main map where you ride a dragon to get from quest to quest. At present the map covers just a few islands, but it looks like I'm in the centre of a nine section map so it should open out later as I complete more quests.
There's no penalty for failing a quest (by losing all your lives) except starting that quest again, and the game autosaves when you successfully complete a quest or do anything else significant. I suspect I'll complete it in 20-30 hours of play.
Your character is a newly dubbed Knight trying to save the Kingdom from the evil Dragon Knights and their commander, a black sorcerer. As it's a game for kids, anyone you "slay" flickers and vanishes rather than falling down in a spreading pool of gore.
There are a number of mini-games along the way requiring use of the stylus, such as a mole-bashing game to clear the jousting lists before a tournament, and a catapult-firing game to knock attackers off their siege ladders.
I also bought the Pirate DS game, but I won't start that until I've finished or got bored with this one.
